If I'm using 8" round duct to facilitate
my returns, shouldn't the register boots
and the takeoffs have the same area as
the 8" pipe?
I have the same question with the supply
boots as well. If the area of 8" round is
100 square inches, why then are there so
many boots with dimensions like:
4 x 10, 6 x 10, 8 x 10 ?
It appears none of these boot openings or
takeoffs have adequate cross-sectional areas
to facilitate the round duct size I'm running to
them. Won't the air volume be limited by the
smallest piece in the branch?
I do realize this question is probably stupid, but
my brain short circuited on this for some reason.
Thanks in advance for any help.
